search for empty date

BetterRed · 09-30-2016, 06:31 PM

What's the easiest way to do it (tried #my_date:empty and similar). I found a way, but you wouldn't want to know about it

Perhaps the Advanced Search->What kind of match to use could have 'is set' and 'is not set' options, similar to the rules for column colours & icons.

Doesn't the standard way used for all such queries work, i.e. true or false.

#date:true

#date:false

Of course they do

Dates have long been the bane of my life, sometimes too many, but more often too few
